Application filed August 13, 1898. Serial No. 688,466. (No model.) 7

T0 0/. whom it may concern:

Be it known that I, GEORGE W. SWIFT, Jr., of Bordentown, New Jersey, have invented a certain new and useful Improvement in Mechanism for Making Tags, whereof the follow ing is a specification, reference being had to the accompanying drawings.

My invention comprises mechanism which, combined as hereinafter described and claimed, is adapted to form tags f paper, cardboard, coated textile fabric, or similar material, which tags are reinforced, perforated at the reinforced portion to receive an attaching cord or wire, and provided with any desired imprint at a single operation.

My invention also comprehends certain details of construction hereinafter more definitely specified.

In the accompanying drawings I have shown a machine conveniently embodying the essential mechanisms to make and imprint tags as above set forth. I

In said drawings, Figure 1 is a plan view of said machine. Fig. 2 is an elevation of the front end of the machine, being the end shown at the lower part of Fig. 1. Fig. 3 is a sectional View taken on the line 3 3 of Fig. l in the direction of the arrows upon said line. Fig. 4 is an elevation of the rear end of the machine opposite to that shown in Fig. 2. Fig. 5 is a plan sectional view taken on the line 5 5 of Figs. 2 and 4. mentary end elevation similar to Fig. at, showing a different adjustment of the knife mechanism. Figs. 7 and 8 are vertical sectional views takenv centrally through the perforating-dies, showing the detailed construction thereof. Fig. 9 is a vertical sectional view taken centrally through the reservoir for adhesive liquid and showing the detailed construction of the outlet-valves thereof. Fig. 10 is a fragmentary end elevation of the notching-dics. Fig. 11-is a sectional view taken on the line ll 11 of Fig. 10 iuthe direction of the arrows upon said line. Fig. 12 is a detail view of the ratchet forming part of the shear-shifting mechanism operative in the formation of tag gangs. Fig. 13 is a detail view of the ratchet forming part of the feeding mechanism for the tag-body web. Figs. 14 to 19, inclusive, show difierent products Fig. 6 is a fragv produced by varying the adjustments of the machine, said figures illustrating somewhat diagrammatically the steps in the manufacture, beginning at the left-hand side of the figures and showing thesevered complete products at the right-hand side thereof. Fig. lishows the most elaborate product of the machine, being a tag having a portion reinforced and said reinforced portion perforated, the corners of the tag-body adjoining said perforations being removed and the tag prowided with an imprint.

Fig. 15 shows a tag formed of the same outline as that of Fig. 14, but not reinforced or imprinted. Fig 16 shows a tag in which the corners remain rectangular, the tag-body being rein forced and perforated, as aforesaid, but not imprinted.

Fig. 17 shows a tag in which the corners re- -main rectangular, the tag-body being perforated and imprinted, but not reinforced. Fig. 18 shows a tag in which the corners remain rectangular, the tag-body being perforated, but not reinforced or imprinted. Fig. 19 shows what is known to the trade as a gang of tags, six tags being shown as. connected in series solely at their top and bottom edges by a narrow uncut portionof the tag-body web. In said drawings, A is the main frame or table, supported upon suitable standards A and A I B is the main driving-shaft, provided with the usual tight and loose pulleys B and B and B is a hand-wheel mounted upon the extremity of the shaft B.

B B are duplicate gears loosely mounted upon said shaft 13 and provided with clutchfaces 1) b B B are duplicate clutch-sleeves suitably keyed upon the shaft B and provided 'with clutch-faces b b, opposed to the respective clutch faces b upon the gears B Said clutches are engaged and disengaged by means of levers B fulcrumed upon the frame member a and connected by the link I) with the hand-lever B. The gears B B are respectively engaged with duplicate gears G O, fixed upon the shaft O mounted for rotation in the frame member A (See Fig. Said gears Care provided with eccentric wrist-pins c c, and. the latter are connected by pitmen O Owith toggle-levers 0 C Said levers C are mounted: for oscillation upon the stud-shaft A which is fixed in the frame member 01?, and the levers C are pivotally connected at c with the chase D, the lower shaft member (1 of which is mounted for oscillation within the depending frame members a. Said chase D is connected by links e e with the oscillatory frame E, loosely mounted upon the shaft A and provided at its outer extremity with a springjournaled inking-roller E, the relation of the parts being such that the roller E traverses the face of the type D mounted in the chase D, during the backward stroke of the latter, and during the forward stroke of the chase the roller E is presented against the inking-roller F As shown in Figs. 1, 3, and 4, said roller F is mounted in bearings a upon the frame A, provided with the usual in k-distributing rollersf and rotated by the gear-wheel f, which is fixed upon the extremity of the roller-shaft F and connected by the chain f with the driving-gear F upon the shaft B. The platen G, opposed to the chase D, supports the tag-webX as it is progressed across said platen with a step-by-step movement and operated upon by the various tag-forming elements of the machine.

The cooperation of the various elements of the machine may be better understood by preliminary examination of Fig. 14, which illustrates somewhat diagrammatically the various steps in the manufacture of the most elaborate product of the machine illustrated. At the left of said figure is shown the blank web X, which is progressed in the direction of the arrow between the reinforcing-strips Y, which are progressed step by step in the direction of the arrow marked upon them. Said strips Y are coated with adhesive on their respective faces adjacent to the web X, and disk portions y are punched from the strips Y, com pressed against said web, and, together with the latter, are perforated, as indicated at z. The perforations .2 serve to receive attaching cord or wire, and said disks y serve to reinforce the perforated body of the tag. The corners of the tag adjoining the perforation z are shaped as shown at the right-hand side of said figure, and this is conveniently effected by notching the lower edge of the web X, as indicated at at.

The machine is adapted to receive webs X of differing widths, the width of said web rep- 1 resenting the length of the tags which are formed therefrom, and in order that the wid th of the various sizes of tags may be made in proportion to the lengths thereof I have fixed the perforating mechanism in position upon the frame A and provided means to predetermine and adjust the extent of feeding traverse of said web X during the intervals of operation of said mechanism. In order that the notches at the lower edge of said web may be made in correspondence with the variation in feeding traverse of said web, I have provided means to adjust the position of the notching mechanism toward and from said perforating mechanism and have also provided means to adjust the notching-die vertically with respect to the lower edge of said web to vary the dimensions of the notches therein. The

types or blocks mounted in said chase D to imprint upon the tag-body web X are of course adjusted horizontally and vertically to proper relation with the particular width of tag-body imprinted, so that the respective tag-i mprin ts w shall be centrally located in line with the respective tag-perforations 2, as indicated in .Fig. 14.

Referring now to Fig. 2, H H are guide-rods between which the tag-body web X is fed to the machine, and said rods are conveniently provided with vertically-adjustable guideplates 72, which maintain said web in proper relation to thetag-forming elements of the machine, of which I shall first describe the reinforcing and perforating mechanism. The 'reinforcingstrips Y Yare placed in rolls upon reels I I upon opposite sides of the reservoir J, which contains a supply of adhesive liquid with which the strips Y are coated upon their respective surfaces subsequently presented next to the web X. The coating operation is conveniently effected as follows:

Referring to Figs. 2 and 9, jj are ports in the bottom of the reservoir J, the mouths j of said ports being narrow slots of length somewhat less than the width of the strips Y.

Each of said ports j is provided with a stopvalve J cut away in registry with the reto maintain the rollers J against the portmouths j. The respective strips Y extend from the reels I between the rollers J and i the respective mouths], to which said rollers 1 are opposed.

ID is obvious that when the valves J are open, as shown in Fig. 5), the

liquid adhesive in the reservoir J gravitates through the ports j and is spread upon the strips Y, upheld by the rollers J the strips being evenly and continuously coated with the adhesive as they pass over said rollers J Referring to Figs. 2, 7, and 8, K K are die blocks having ducts 7a, through which the strips Y Y extend. The tag-web X extends horizontally between the die-blocks K K and the strips Y Y, the normal position of the parts being that shown in Fig. 7, wherein the die-plungers K K are withdrawn from the path of travel of the strips Y. K K reciprocate from the position shown in Fig. 7 to that shown in Fig. 8, and in their travel punch disk portions y from the respectiVe webs Y Y, compress said portions upon the web X, and perforate the latter, as shown at z in Fig. 14. The plunger-head K is con- The pl uuge rs slideway 071?, fixed upon the gear M.

nected by the link 10 with the lever K fulcrumed at is upon the frame-standard A and connected by the pitman K with the cam K fixed upon the shaft B. The link K which is also connected at the top of the lever K extends to the lower end of the lever K", which is fulcrumed at it) upon the frame A and is connected at its upper extremity with the plunger-head K by the link k sothat the cam K serves to oppositely reciprocate both of the plungers K and K It will be noticed that a double punching operation is effected by the single reciprocation of the plungers K and K The plunger K being loosely mounted for reciprocation in the plungerhead K is thrust outwardly therefrom by the spring 10 and normally assumes the position shown in Fig. 7 with respect to the central plunger-stem k Said stem registers with the passage-way it in the plunger K, form- 'ing, with the latter, a secondary set of punching-dies. The plunger K having a longer stroke of reciprocation than the plunger-head K the excess of movement of the former is sufficient to carry the die-stem 10 through the tag-web X and the reinforcing-pieces y y, forming the perforation z therein, as shown in Fig. 8, the plunger-head K and stem 10 shifting with respect to the plunger K during the latter portion of its stroke. The strips Y Y are drawn from the reels I I over the rollers J and through the die-blocks K by the feed-rollers L L The roller L is provided with a ratchet l, engaged by the pawl Z upon the pawl-disk L, which is connected by the pitman L with the cam L upon the shaft B. (See Figs. 2 and 5.) Said cam L serves to reciprocate the pitman L and partly rotate the roller L at each revolution of the shaft B, so that the strips Y are shifted step by step to be punched throughout, as indicated in Fig. 14. The roller L opposed to the roller L, is mounted eccentric-ally upon the short shaft Z journaled in the standard A and provided at its inner extremity with a lever 1, connected by the spring Z with said standard, the parts being so related that said spring tends to shift the center of rotation of the roller L toward the roller L to firmly grip the strips Y Y fed between said rollers. The web X is intermittently progressed by the feed-rollers M M an amount predetermined and adjusted in accordance with the dimensions of the tags to be produced as follows:

Referring to Figs. 1, 4:, 5, and 13, M is a gear-wheel fixed upon the shaft B and engaged with the gear-wheel M, fixed upon the shaft m, journaled in the standard A M is an eccentric-stud radially adjustable in the The rack-pitman M is journaled at one extremity upon said stud M and is yoked at the other extremity for engagement with the gear-wheel M fixed upon the pawl-disk M Said yoke and disk are loosely mounted upon the shaft M and the pawl m upon the pawl-disk M engages with the ratchet-wheel M fixed upon the shaft M Said shaft, is mounted for rotationin the standard A and in the frame member a is provided with the hand-wheel M and. connected by the miter-gears m with the shaft M upon which is fixed the web-feeding roller M Said roller M is opf posed by the pressure-roller M mounted in the usual spring-bearings, and said rollers are connected'at their upper extremities by respective gears m and m The slideway 012 is conveniently graduated to represent fractions of an inch of circumference of the feed-roller M so that the eccentric-stud M may be directly adjusted in accordance with the size of the tags to be produced to rotate the roller M the extent of one tag width at each stroke.

The mechanism for forming the notches m (shown in Fig. 14) is conveniently located in the line of travel of the web X, between the die-blocks K K and the feed-rollers M M and is constructed as follows: Referring to Figs. 1, 2, 5,10, and 11, N is a cam fixed upon the shaft B, engaging with the roller n upon the lower extremity of a lever N, mounted for oscillation in the frame A. The upper extremity of said lever N comprises a shaft 71 upon which is journaled a link N serving to actuate the notching-plungerN ,mounted for reciprocation in the die-block N The forward extremity of said plunger N is shaped in conformity with the notches as (shown in Fig. 14) and registers with a similarly-shaped die-plate 01 As the notches m are centrally located between the perforations in the tag-body web, it follows that the notching-plunger must be shifted horizontally away from the perforating mechanism in accordance with the increase of Width of the tags manufactured. The notches a". also vary in dimensions in proportion to the size of tags produced. I have therefore found it convenient to mount the die-block N upon an inclined slide-bearing a upon the frame A, to which it is secured by the screw-clamp N The angle of inclination of said slidebearing is such that when the die-block N is shifted horizontally from one graduation to another (representing the standard sizes of tags) the die-block'is also raised or lowered in accordance therewith to proportionately vary the dimensions of the notches produced in the edge of the web X, the long pivotal connection for the link N at the top of the lever N permitting such adjuitment.

After passing in its feeding traverse the reinforcing, perforating, notching, and printingmechanisms above described the tag-body web X may be sheared to form disconnected tags, as shown in Fig. 14, or may be slit and sheared to form tag gangs of differing numbers connected at top and bottom, as shown in Fig. 19, the particular operation of the shearing mechanism to sever or slit the web X and the number of tags in the gangs aforesaid being predetermined by adjustments of said mechanism, as follows: As shown in Fig. 6, O is the oscillatory shear-blade, fulcrumed at 0 upon the shear-frame 0', upon which is fixed the ledger-blade O The cam P, fixed upon the shaft B, engages the roller 1) upon the pitman P, and the latter is provided at its opposite extremity with a' yoke P pivoted to the shear-blade O at p, said blade being thereby oscillated upon its fulcrum 0 once during each revolution of the shaft 13 and cam P. When it is desired to sever the web X by the stroke of the blade 0, it is necessary that the overlap of said blades 0 and 0 shall be coextensive with or exceed the width of the web X fed between them by the rollers M M When, however, it is desired to merely slit said web in the formation of tag-gangs, the overlap must be adjusted to equal the length of the slit desired. In order that said blade 0 may be adjustably shifted with respect to the blade O with a resulting increase or diminution in the length of said overlap, the extremity of said pitman P comprises a pivoted sector P which is clamped in adjusted position with respect to said pitman by means of the set-screw 19 To permit of the adjustment of the shears and frame 0 toward and from the notching mechanism in accordance with the aforesaid adjustment of the latter for differing widths of tags, the yoke P is mounted in the slideway P upon said sector P being secured. thereon by the set-screw 19 the frame 0 be ing adjustably mounted upon the frame A, as follows: Referring to Figs. 1, 3, 4, 5, and 6, the vertical fixed member A of the frame supports the frame member A which is vertically adjustable thereon by means of the screw A which is mounted for idle rotation in A, but in threaded engagement with the boss A upon A the screw A serving to secure the parts A and A in adjusted position. The frame member A is horizontally adj ustable upon the member A toward and from the notching mechanism, being secured in adjusted position by the set-screw A". It is obvious that by adjustment of the sector P upon the pitman P and of the yoke P and the frame A the shears may be set to operate in any desired position with respect to the web X. However, to effect the double operation of slitting and severing said web necessary in the production of tag gangs the shear-frame O is mounted for vertical reciprocation upon the frame member A upon which it is automatically raised and lowered by the cam Q and the opposed spring 0 The cam Q is fixed upon the shaft Q, mounted for rotation in the brackets a of the frame member A and opposed to said cam is a friction-roller o, journaled in the shear-frame O, the latter being slotted, as indicated at 0 to permit of the vertical movement of said frame with respect to the shaft Q. The spring O connecting the frame A with the frame 0, serves to uplift the latter to the limit of the slot 0 when the roller 0 is freed from engagement with the cam Q When it is desired to set the shearing mechanism to form tag gangs, the shear-frame 0, being maintained in its upper position, the frame A is adjusted vertically until the lower corner of the blade 0 is at the desired point in the tag-body web above the lower edge there of. The sector P is then shifted to eifect the desired extent of overlap of the blade 0 upon the blade O The successive strokes of the shear-blade 0 when thus adjusted will produce a series of slits in the web X without severing the latter until the shear-frame O is thrust bodily downward by the revolution of the cam Q", whereupon the lower corner of the blade 0 is carried below the edge of the web X, and the changed relation of the parts increasing the overlap of the shears the web is thereby completely severed. The number of tag-slits in a gang is therefore dependent upon the sequence of revolution of the cam Q and shaft Q with respect to the cam P and shaft B, which is predetermined and adjusted as follows: Referrring to Figs. 1, 4c, 5, 6, and 12, the crank-arm R is fixed upon the shaft 13 and provided with an eccentric-stud R, adjustably mounted in the slideway 4", upon which is journaled one extremity of the rackpitman R which is yoked at the other extremity in engagement with the gear-wheel R fixed upon the pawLdisk R. Said yoke and disk are loosely mounted upon the shaft Q, and,as shown in Fig. 12,the pawl Wong-ages the ratchet-wheel Q, fixed upon said shaft. The stud R may be radially adjusted in the slideway 1' so that said pawl r is caused to shift the ratchet-wheel Q, shaft Q, and cam Q the extent of any aliquot n umber of teeth q. For instance, the number of said teeth illustrated being twelve,the stud R may be set, as indicated in Fig. 6, to shift said ratchet and cam theextent of two teeth at each revolution of the shaft B and slitting stroke of the shear-blade 0, so that upon the sixth stroke of the latter the cam Q will have made a complete revolution. The shear-frame Q being thereby depressed, said stroke of the shear-blade 0 will completely sever the web, producing a tag gang, such as shown in Fig. 19. The stud B may be similarly adjusted to increased eccentricity to produce gangs of four, three, and two tags, respectively. When, however, it is desired to completely sever the web X at each stroke of the shear-blade O,the stud R is shifted to concentric relation with the shaft B, as indicated in Fig. 4, and the cam Q being in the position shown in Fig. 6 the shear-frame 0 remains stationary and the parts just de- T upon the blade 0 serving to facilitate the delivery of the tags upon said chute.

To facilitate the counting of the tags or gangs produced, the shaft m is provided with a crank-arm U, connected by the link U with the pawl-lever U The pawl u upon the latter engages the ratchetwvheel U fixed upon the shaft U and the striker *a upon said shaft serves to operate the bell U at intervals determined by the relation of the, parts.

Itis obvious that various modifications may be made without departing from the spirit of my invention. I therefore do not desire to limit myself to the precise construction which I have shown and described.
